Returning from your magical seven-day vacation can be absolute hell. Where did the Minnesota Vikings' killer instinct go?

I use two factors to rank these teams: A) how they looked through seven weeks of play and B) how they're set up going forward. I'm at @CSimms QB on Twitter; hit me up if you feel like venting.
